Re: Gravity Vehicle C

Now with a design like that, how do you prevent the bearing from slipping out of the holder? The image I've linked to above shows a a screw used to tighten the wood and grasp the bearing. Any other options? A couple self-threading set screws coming in from the top and bottom of the wooden holder mi...

Re: Gravity Vehicle C

How do you mount the bearings to the chassis? My thought is to use a block that is mounted underneath the chassis, with a hole large enough for the OD of the bearing to fit in. With this method though, I'd imagine that the bearing would fall out of the block when braking occurs. After looking throu...

Re: Gravity Vehicle C

Oh... We get them for about $17 a piece... You have to realize that we put about $100 into our vehicle last year, $80 in bearings(impregnated bronze, big mistake) and wheels.

Re: Gravity Vehicle C

Hmm... I've always just bought mounted bearings, is there any bennifit to building your own mounting blocks? I assume it'd be cheaper, but unless you have access to some nice tools you'd also loose some percision(ie. the bearing might have a small amount of play relative to the body) right? Illusio...

Re: MagLev C

Mr. Chalker (not sure which one), can you please update the Maglev page on soinc.org? I remember someone saying that instructions to build your own track would be made available on the national website, but nothing has been uploaded as of now. Thanks
